Mueller - Mueller P7505 Pure steam generator

Applications & Use Cases

• Sterilisation of process equipment and pipelines in pharmaceutical and biotech manufacturing.
• Humidification in cleanroom environments where high-purity steam is critical.
• Direct steam injection for product heating where steam purity is paramount.
• Autoclaves and sterilizers requiring a consistent supply of pyrogen-free steam.
• Sanitisation processes in the food and beverage industry, particularly for sensitive products.

Typical Specifications

Typical capacity

Pure steam generators of this class commonly offer capacities ranging from several hundred to over 5,000 kg/hour, with this specific model indicating a high output.

Power supply

Units of this industrial scale typically require a 3-phase electrical supply, commonly 400V or 415V in the UK, for heating elements and controls.

Construction material

Pure steam generators are invariably constructed from high-grade stainless steel (e.g., 316L) for all wetted parts to prevent contamination and ensure steam purity.

Control system

Modern units often feature PLC-based control systems with HMI touchscreens, such as Allen-Bradley, for precise operation and monitoring.

Feedwater requirements

These generators typically require demineralised or reverse osmosis (RO) treated water as feedwater to produce pure steam and prevent scaling.

Steam purity

Pure steam generators are designed to produce steam meeting pharmacopoeial standards (e.g., EP, USP) for WFI quality, free from pyrogens and other contaminants.

Footprint

While specific dimensions vary, units with this capacity are typically skid-mounted and require a dedicated plant room space for installation and maintenance access.

Frequently Asked Questions

• What is the difference between pure steam and plant steam?

  Pure steam is generated from treated water (e.g., RO, demineralised) in a dedicated generator, ensuring it is free from non-condensable gases, boiler additives, and particulates. Plant steam, conversely, is generated from untreated or less-treated water and may contain impurities unsuitable for direct contact with products or sterile environments.
